Problems solved by technology

Both ends of the existing artificial dam body are directly connected to the side of the road, resulting in a very short seepage path at the joint, which easily causes water to leak from the joint between the artificial dam body and the side of the road

Abstract

The invention discloses a dam body connecting structure and a construction method of the dam body connecting structure. The dam body connecting structure comprises a roadway and a dam body which is used for partitioning the roadway. The roadway comprises a roadway bottom plate, a roadway top plate and two roadway edges which are connected between the roadway top plate and the roadway bottom plate.A supporting base plate is arranged on the roadway bottom plate. The dam body comprises a supporting layer, an impermeable layer and a concrete layer. The supporting layer, the impermeable layer andthe concrete layer are arranged in sequence in the roadway extending direction. The impermeable layer is arranged between the supporting layer and the concrete layer in a filling mode. The two ends ofthe concrete layer are embedded into the two roadway edges and connected with the roadway edges in a sealed mode. According to the dam body connecting structure and the construction method of the dambody connecting structure, the multi-layer structural design is adopted by the dam body of the dam body connecting structure, and the permeation resistance performance and the structural strength ofthe dam body connecting structure can meet the water storage requirement of an underground reservoir.

Description

technical field [0001] The invention relates to the intersecting fields of mining engineering and water conservancy engineering, in particular to a dam body connection structure and a construction method thereof. Background technique [0002] At present, the construction of retaining dams for distributed underground reservoirs in coal mines is still being further studied and designed. The construction of sluice gates and sluice walls is regulated in the "Coal Mine Safety Regulations" and "Coal Mine Water Prevention and Control Regulations", which are mainly based on the perspective of water prevention and control, without considering the long-term role of underground reservoir water storage; The construction of the dam body has been regulated in detail, but the construction of the dam body of the surface reservoir and the construction of the retaining dam of the underground reservoir are obviously different. [0003] Comparing the dam body of the underground reservoir of th...
